The red spider has a strong reproductive capacity, and can reproduce a generation in about 5 days at the fastest. This insect likes a hot and dry environment.

If you find that the color of flower leaves is abnormal, you should carefully check the back of the leaves. When individual leaves are damaged, you can remove the insect leaves; when more leaves are damaged, you should spray pesticides as soon as possible for prevention and control. Commonly used pesticides include cypermethrin, trichlorodimethoate, dimethoate, cypermethrin, and cypermethrin. For home flower cultivation, you can prepare a flower sprayer. Add cypermethrin, cypermethrin, or cypermethrin to 400 ml of water (equivalent to 2000 times liquid), or add cypermethrin or dimethoate 8 drops (equivalent to 1000 times liquid), shake well after adding the medicine, and then spray. Spraying requires uniformity and thoughtfulness, especially pay attention to spraying the back of the leaves. It is best to move the potted flowers outdoors when spraying. If you spray indoors, do not approach food or utensils. After each use, pour out the excess liquid and wash the sprayer with clean water.
